"application ineaV november 18,1925; semi Nq. @ascen-l r To all 'whom t may concern.' d Be it known that LWViLLIAM WERNER, a citizen of the United States,- residing at MeXia, Texas,.hav`e invented a certain new and useful Improvement in' Standing-Valve- Releasing Means, of which the followingl is a specification. 'f

My invention relates to means for raising the standing valve, in a deep `well reci rocating pump, from its seat so'that the uid above the valve may bedrawn out of the tubing from above the'said valve vwhenfthe tubing is being raised'from the well...

It is a common difficulty, when the tubing of a deep welly is removed, especially in oil wells, that` the standing valve at .the lower end of the tubing remains closed and cannot be raised, the tubing therefore remains full of oil after lthe"plunger'has'been withdrawn, and each section of the tubing, when unscr'ewedfr'oin the adjacentllower section, spills its contents over the floor of the derrick, not. only wasting the oil, but causing inconvenience and discomfort tothe operators.`

yIt is an object of my invention to provide mean'swhereby the standing valve may be i raised from its Lseat before the tubing'is ywithdrawn from the well, thereby allowing the oil todrain out of 'the'tubing, and avoidingl the usual waste o fj'oill ordinarily experienced. f

Iris desa-ed thatthivaive be raised with a minimum amount ofy `manipulation and in a positive manner' which will'not fail `tol work under all circumstances. ,I

Fig.l 3 is a similar section on the plane 3-3 lof-Fig. 1. Figs. 4 andV 5 are similar transverse sections on the planesl-l andA 5-5 of Fig. 1, respectively. yLike numerals of reference are applied to like parts in all the views. i Y i,

In Fig. 1 the pumpbarrel 1 Ais shown as positioned within the upper end of the liner 2, projecting into the casing' inthe v usual manner. The y casing 3 has a shoe at its lower end, and the' liner 2 has la shoe vl5. The lower end ofthe liner isi perforated at l6 to allow the entrance of fluid vfrom the 'well therethrough.' Thelliner has atits' lentraine vlower end atube7 connectedto the perforated portion byv a collar 8'. `A cap 9 closes PATENT OFF-ICE# the `lower end of the 'tubel 7, preventingthe ,v

It has the usual ballvalve at its lower end, fitting within thevalve cage Y11. The standing valve in this constructionis housed within a nipple'12ofslightly` larger A diameter than the. kworking barrelfl, and is "I 'connected to 'the'lower end of the'f'working :barrel byfya collar 13. The valvefseat 14 lcomprisesja somewhat disc shaped block threaded 'for engagement within the lovfver,v

` end Iofthevalve h0using12, and has a cen- V.tral downwardly tapered seat l15 therein to receive'ja valve 16 whichis tapered downwardlyto'fit `:within the valve seat15,'the lower end :being somewhat truncated,4 and I being positioned to lit within the upper end kof a tube l17 which will be later described. 'The upward movement ofthe .valve 16 is Y limited by la valve cage 1,8 which is screwed lto the valve seat, as shown at 19, inther usual lnianner.V y

A sleeve is threaded to engage thelowerend of the valve housing, 4s'aid'sleeve havi ing a swivel connection at fits lowerend with a coupling member' 21. Tofaccom lishthis swivel `connection,'theY lower kenv *gofjthe ksleeve 20 is,` formed ,with l a short inwardly turned flange 22,' saidjfflange being adapted externally for attachment l@nits outer Aside to a'perforated pipe 25-"which servesujas a mudv anchor.V j Said 'mud anchor Ventends lower end is c -osed b means of' anplug25.

'to engage below aila'nge 2301i the upperend i ofthe collar 21.! Said.v collar 21 -is` threaded;

"The mud anchor isfa apted to 'be held ynonj rotatably within liner 2,` and to accomplish this purposea series of springs27 vare secured on the outer. face of the mud anchor, and adapted to bear a ainsty the inner face of' thelinerf. Said sprmgs` 2'( are straps `of resilient metal bowed outwardlyinidwayof theirendSto againstthe liner, ,The

upper and lower ends are secured to a pin or rivet 29 which extends through the end of the spring and through a slot 80 in the mud anchor. The spring is thus adapted to be compressed to fit within liners of different sizes, and to press tightly against the liner to resist rotation of the inner pipe or mud anchor. If desired', the strap of metal which forms the spring 2 7 may be undercut, and provided with a sharp outer edge 31, as shown in Fig.l 41. This sharpened edge is adapted to cnt into the outer pipe when it is attempted to rotate the mud anchor in a right hand direction, and more efficiently resist the attempt to rotate the same.

On the inner side of the collar 21 is threaded a pipe 32 which is imperforate, and acts as a gas anchor tov prevent the accumulation of gas within the chamber of the standing valve. This pipe extends a considerable distance below the valve, its length being determined by the particular installation in which it is used.

The collar 21 has a spider adapted to support the tube 17 previously referred to. This'spider compri-ses a central ring 33 connected with the collar by means of radial arms 34 as shown in Fig. 3. The ring 33 is threaded on vits inner side to engage the threaded lower end 35 of the tube 17. The threaded engagement is a so-called left hand engagement, and the tube is therefore adapted to be disconnected from the ring by rotation in a righthand or clockwise direction as viewed from abo"ve. A longitudinal slot. 36 is cut through the tube 17, and a diametrical pin or bar 37 extends through said slot, and is secured at its opposite ends within the housing 2O (see Fig. 2). The bar is upset or riveted at each endl so as to be fixed inposition within the valve housing. Y 1 In operating this device, it is obvious tha in the ordinary operation of the pump the swivel connection above described will have no particular' function. When it is desired first withdrawn from the pump barrel. In doing` so, the pump barrel will be filled with 'oil following the plunger Aupwardly to the tion.

surface. This oil willv be,r discharged from the barrel Iso as to empty the same by rotating the pump barrel in a right-hand direc- -This will cause the rotation of the sleeve 2O relative to the collar 21 and the Vremainder of the apparatusbelow. By rotating the sleeve 20, the cross bar or pin 37 will act to rotate the tube 17 also, and asthe through the action of the springs 27. Unscrewing the tube 17 will cause it to move upwardly against the lower end ofthe valve 16, thus acting to raise the valve from its seat into the position shown in Fig. 1. This will release thev oil above the valve, allowing it to drain away, so that the pump barrel and tubing may be withdrawn upwardly from the well, together with the standing valve secured thereon. y

The advantages of this construction will be obvious to One skilled in the art. The valve 'may be raised from its seat sufficiently to drain the oil from the pump barrel by only a few rotations of the barrel. As the usual joints in the pipes connected with the pump barrel are threaded in a right hand direction, they will not tend to unscrew by the rotation thereof in a right hand direction. leasing tube 17, will be a positive one, and the tube will be screwed upwardly, tending to quickly release the valve. It is simple and positive in its action, and may be adapted for usel with pumping devices of different makes. While I have shown it adapted for use in a pump of the construction described, it is obvious that it is adapted for use with pumps of quite different form and construction.

I-Iaving thus described my invention, what I claim as new and desire tov protect by Letters Patent is:
